Abstract (en)

[origin: EP0965279A2] A succession of receivers (12), each filled with a set quantity of material, is conveyed along (13) the roaster (11). Each receiver has a perforated base (14). Hot gasses are passed from below, through the perforated base and up through the material. An Independent claim is included for the corresponding equipment, in which gas introduced, fluidises the material. Preferred features: Underneath, the receivers are open and have a wall at the front or rear, moving over the fixed perforated base. The receivers are frames closed on all sides and open above and below. Side walls are fixed, forming a trough with a sieve base, along which front and rear walls move. At the extraction point (47) receivers leave the sieve base and the rear wall (29) transfers the material into an intercepter (30). Conveying is linear or follows a horizontal closed curve, with the sieve base extending under part of it. The curve is circular, the receivers shaped as sectors or rings. The receivers are separate containers, each with a perforated base. There are e.g. three heating zones (31, 32, 33), with separate gas extraction zones, optionally in correspondence. These are followed by cooling zone(s), a gas lock separating them from the heating zones. The cooling region is used for moisture conditioning, with interconnection(s) to the heating zones. Conveying speed is adjustable to vary roasting time. The base has perforated and closed regions, distributed evenly or unevenly over the surface.
